Hey Mona,
I'm no expert, but do read a lot of what hybridizers do. In warmer climates and for those who have heated greenhouses a seedling can be blooming size by 6 or 7 months. Then it's no different than a single fan that increases to 5 or 6 fans in a few months. I've had that happen. Also, fertilizing with a diluted solution of water soluable fertilizer twice a week or more helps, plus the other additives used in the soil such as alfalfa, slow release fertilizer and such to get it to bloom in 6-7 months. Then if it is a fast increaser it can multiply that fast. I'm sure Fred will chime in with his expertise.
